Nitto B132 Hanafuda Randonneur

The hump shoulder refers to a gentle rise in the bar near the stem clamp. This design allows for a more upright, natural wrist angle when your hands are on the tops, which significantly reduces fatigue during long days in the saddle.

These bars use a 25.4mm stem clamp diameter, which is a classic standard. If you are using a modern threadless stem with a 31.8mm clamp, you will need a shim or a specific 25.4mm stem to make them compatible.

The 74-degree flare angle provides a wider, more stable platform when you are in the drops. This extra width offers better leverage and control, especially when navigating rougher terrain or riding a fully loaded touring bike.

Yes, the B132 features a 20mm inner diameter, which is compatible with most standard bar-end shifters. The aluminum construction is durable enough to handle the installation of these shifters securely.

The 500mm width is ideal if you prefer a more stable, upright position or if you are running a wider tire setup that benefits from extra leverage. The 460mm option is better suited for riders who want a slightly more aerodynamic profile while still maintaining the comfort of the randonneur shape.
